Usage Examples

Example 1: Basic Color Selection

Using the picker to let a user choose a theme color.

C# - Theme Selector

private void OpenThemePicker()
{
                var pickerForm = new Form();
                var picker = new SiticoneColorPicker();
    
                // Set initial color
    picker.Color = Properties.Settings.Default.ThemeColor;
    picker.ShowOldColor = true;
    picker.Dock = DockStyle.Fill;
    
    picker.ColorChanged += (s, e) => 
    {
                ApplyThemeColor(e.Color);
    };
    
    pickerForm.Controls.Add(picker);
    pickerForm.ShowDialog();
}

Example 2: Advanced HSB/Hex Access

Retrieving advanced color data from the event arguments.

C# - Color Data

private void OnColorSelected(object sender, PickerColorChangedEventArgs e)
{
                // Access HSB (Hue, Saturation, Brightness) values
                Console.WriteLine($"Hue: {e.HSB.H}, Sat: {e.HSB.S}, Bri: {e.HSB.B}");
    
                // Access Hex string directly
    txtHexCode.Text = "#" + e.Hex;
    
                // Use the standard Color struct
    pnlPreview.BackColor = e.Color;
}
